What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Bremont Supernova

The Bremont Supernova is praised for its new ENG375 movement, big date, and power reserve indicator, with its 40mm steel case featuring mixed finishing and an integrated bracelet. Owners note good but not great lume, well-balanced proportions, and a premium feel for its price, despite a 173-gram weight. Some community members find the design derivative and the £8,000 price tag overly optimistic, with mixed views on the date window and crown guard. The proprietary Trip-Tick case construction offers shock protection, and the movement provides a 65-hour power reserve. Overall, owners and reviewers highlight the integrated bracelet and proprietary movement as key strengths of the Bremont Supernova.

Longines MASTER COLLECTION

The Longines Master Collection is widely praised for its excellent fit and finish, heritage-inspired design with engraved Breguet numerals, and dial textures, offering tremendous value. Owners appreciate its dressy, thin profile and the use of ETA movements, with specific models featuring triple-date, annual calendar, or moonphase chronograph complications. Some reviewers note the subdial cutting off the "7" on the Small Seconds model, the lack of micro-adjustments on the bracelet for a perfect fit, and a somewhat homogenous case finishing. The 30m water resistance on the Annual Calendar is considered light, and the traditional styling is not as popular as sport watches. The Master Collection Chronograph is lauded for its classic, vintage styling. Overall, owners rate the Longines Master Collection highly for its value and classic dress watch aesthetics.

From video reviewers
